This invention relates to thread-guides for spinning, twisting'and other analogous textile' machinery, and the invention has for its object't'o improve theattachn'ient of these guides and to facilitate the renewal of guides when necessary.

It is usual to employ guides composed of some suitable hard and durable material such as'porc'ela'in or hardened steel, and these by reason of their composition are manufacanalogous 'tezttile machine is retained in place by means of an external spring anchored at one end to and embracing the part holding said guide and being so formed as to project through a slot in said part in order to engage a notch on the periphery of the guide, whereby rotary and vertical movement of the guide are prevented.

One constructional form of the invention is illustrated in the accompanying drawings, in which Figure l is a side elevation of a part of a textile machine into which a thread guide is fitted, Figure 2 is a plan view, and Figure 3 is a sectional plan view on line 2-2 of Figure 1.

1 represents a metal bracket, or other part of a spinning or like machine, which is apertured to receive a thread-guide or peteye 2.

This pot-eye 2 is slotted radially at 2* in order to permit the yarn or thread to have access to its central bore, and externally said pot-eye 2 is formed with a notch 3 or other equivalent means of securing interlocking engagement with a knee at or its equivalent formed in a steel spring 5 adapted to encircle a portion of said bracket 1 (which is slotted at 1 for admittance of said knee 4%) to which bracket one end of said spring 5 is anchored by being turned in radially and inserted in an aperture 5 formed for its reception in the side of the bracket 1. The position of this aperture 5* relatively to the For example these porce-' pct-eye.

it will be seen that the above described ar- -angement constitutes-a very simple means of retaining pot-eyes or thread-guides in place and enables any one to beremoved and renewed with the greatest facility merely by exerting pressure. to spread the retaining ring sutliciently to release it from engagement with the pot-eye or guide.

VJ hat we claim is 1. In spinning, twisting and other analogous textile machines, an apertured part to receive a thread guide, a radial slotfserving as a thread passage into said apertured part,

a thread guide fitting in said apertured part, said thread guide-having a central bore and a radial slet leading thereinto and said radial slot being'adapted to register with said thread passage in said apertured part, a peripheral slot in said apertured part, a radial aperture in said apertured part, a spring having one end. anchored in said radial aperture, said spring encircling a portion of said apertured part, and means to cause said spring to engage and hold said thread guide in said apertured part.

2. In spinning, twisting and other analogous textile machines, an apertured bracket to receive a thread guide, a radial thread passage in said bracket, a thread guide fitting into said bracket, said thread guide having a central bore and a radial thread passage therefrom adapted to register with said thread passage in said bracket, a peripheral slot in said bracket, a radial aperture in said bracket, and a spring encircling part of said bracket and having one end anchored in said radial aperture, said spring engaging and holding said thread guide inv said bracket.

3. 1n spinning, twisting and other analogous textile machines, an apertured bracket to receive a thread guide, a radial thread passage in said bracket, a thread guide fitting into said bracket, said thread guide having a central bore and a radial thread passage therefrom adapted to register with said thread passage in said bracket, a peripheral slot in said bracket, a radial aperture in said bracket, and a spring encircling part of said bracket, one end of said spring being bent into said radial aperture in said bracket, and part of sald spring extending through said peripheral slot to engage and hold said thread guide in said bracket.

into said bracket, said thread guide having a central bore and a radial thread passage therefrom adapted to register with said; thread passage lnsald bracket, a perlpheral notch on said thread guide, a peripheral slot insaid bracket, said peripheral notch and said peripheral slot being adapted to register, a radial aperture in said bracket,

- and spring encircling part of said bracket,

one end of said spring being, bent ntov said radial aperture in said bracket and part of said spring extending through said peripheral slot to engage said notch on the periphery of said thread guide and to hold said guide in said bracket.

5. In spinning, twisting and other analogous textile machines, an apertured bracket to receive a thread guide, a radial thread passage in said bracket, a thread guide fitting into said bracket, said thread guide having a central bore and a radial thread passage therefrom adapted to register With said thread passage in said bracket, a pcripheral notch on said thread guide, a pcripheral slot in said bracket, said peripheral notch and said peripheral slot being adapted to register, a radial aperture in said bracket, and spring encircling part of said bracket, one end or said spring being bent into said radialaperture in said bracket, said spring being formed to project through said peripheral slot to engage said notch on the periphery. of said thread guide and to hold said guide in said bracket. I

6. In spinning, twisting and other analogous textile machines, an apertured bracket to receive a thread guide, a radial'thread passage in said bracket, a thread guide fitting into said bracket, said thread guide having a central bore and a radial thread passage therefrom adapted to register with said thread passage in said bracket, a peripheral notch on said thread guide, a peripheral slot in said bracket, said peripheral notch and said peripheral slot being adapted to register, a radialaperture in said bracket, and spring encircling part of said bracket, one end of said spring being bent into said radial aperture in said bracket, and a knee formed on said spring," said knee projecting through said peripheral slot to engage said notch on the periphery of said thread guide to hold said guide in said bracket.

In testimony whereof We afiix our signatures.
